Question

At a golf ball factory, 60 golf balls were inspected and 48 of them passed inspection. Out of 2,500 golf balls made at the factory, about how many would you predict would fail an inspection?

Answer 1

failed in 60 balls=60-48=12
failed in 2500 balls=\[\frac{12}{60} *2500=500\]

Answer 2

500

Explanation:

48 of the golf balls passed inspection. This means that

60-48 = 12 golf balls failed inspection.

This gives us the ratio 12/60 = 1/5 for the number of golf balls that fail inspection.

Out of 2500, this means we would expect

1/5(2500) = 2500/5 = 500 golf balls to fail.
